This uneven erotic horror film from cult director Jesus Franco stars Britt Nichols as Luisa Karlstein, who visits the family mansion in Portugal to see her dying grandmother, the Baroness (Carmen Carbonell). Luisa soon learns that the family is cursed with vampirism, but moves into the mansion regardless, only to encounter strange and sexual phenomena. But murders have been occurring in the adjacent seaside village, bringing Inspector Ptuschko (Alberto Dalbes) to investigate. Anne Libert, Daniel J. White, Fernando Bilbao, and Howard Vernon (as Dracula) co-star, while frequent Franco collaborator Lina Romay makes an early appearance. Despite some well-handled murder scenes and surreal eroticism, the film's disorientingly cheerful photography and lack of genuine menace prevent it from being truly effective.
